Angry not enough air flow
New to cpap. Using for one month with no problems until last week. I feel short of breath and cant get enough air. When I start to fall asleep I wake up gasping. The airflow on the nasal pillows feel reduced. I checked the tubing and connection for leaks, cleaned the filter and tubes but still no increase in air flow. Has anyone else had this problem? need help

RE: not enough air flow
Welcome

You're in the right place, calliopy2!

The folks here will help you fine tune that new machine so you can get the most out of it.

I think everyone will want to know the exact model # of your Respironics machine
for starters as well as your mask make & model.
Then folks here can help you figure out what pressure(s) you are set for and what to do next.
(Doctors do not have time to help out beginners much so that is why this website is here!)

Hang in there and never quit! Smile

RE: not enough air flow
As Shasti said, more info on your machine and present settings is needed to narrow down a cause.
Things that come to mind:
1) Using an Auto machine and having too low a starting pressure range. Some noobe's get started at 4 cm-H2O which is generally too low.
2) Using the ramp feature. Most people do better with the ramp turned off.
3) Too small nasal pillow cushion.

Hi calliopy2,
WELCOME! to the forum.!
Are you using ramp? if so, you might either decrease the time it runs or turn it completely off. Let us know what your pressure is and what kind of machine and mask you have so that people can better assist you.
Hang in there for more responses to your post and much success to you with your CPAP therapy.

RE: not enough air flow
I felt like I could not breath because the pressure was making it hard to exhale. On my system one I put it in CFLEX mode which lowers the pressure while you exhale. It did the trick. It is also called expiratory pressure relief

RE: not enough air flow
Usually it takes a while to acclimate to pressure as high as 10cm & above.

The feeling will go away after some time when you slowly get used to it.
When you wake up and think your machine is running, but not working, check your exhaust vents and you'll
likely feel the air blowing out.
Then you'll know you have adapted.

RE: not enough air flow
If you think the reduced airflow is due to a mechanical (rather than software) problem, in addition to the cleaning and looking for tube leaks you've already done, check the connections between (1) the tubing and the mask, and (2) the tubing and your machine. Also check to make sure there are no kinks or sharp corners in your tubing. I hope you have success!

Hi calliopy2,
Welcome to the forum. Please filled out your profile.

What pressure are you using and if you are using the ramp, turn it off.
If your pressure is too low, you will feel as if you are not getting enough air.

Also, what nasal pillow mask are you using. You can try a size larger pillow to see if that helps.

RE: not enough air flow
To all, thanks for all the help. Sorry for the response delay. I was hospitalized for pneumonia and just got discharged today. Having a hard time finding out info. The bill of sale lists each part by number not names and on the machine, the supply company has placed their plaquard info probably hiding what I am looking for. Did find out the problem. Inside the tubing is another flimsy soft plastic coil which was twisted. In the hospital, I had no problems with the cpap. I suspect, like my wheelchair, I must have a walmart quality machine. I did take the hospital tubing and nasal mask. They appear to be of a better quality
